Photoelectric Detector

The LG-900 series detectors are reflection type optical (LG-916) and photoelectric detectors developed for medium distance detection applications. The LG-916 adopts glass fiber at the tip end and can be protective enough against the external turbulent light because of pulse modulation system as the light projection source. The LG-930 also uses a pulse-lighting method, it is practically unaffected by disturbance light, furthermore, featuring a hybrid structure with the all light-projecting, light-receiving, amplifying, and waveform-shaping sections built into the unit to offer a compact design with easy-to-operate functions. By simply attaching the reflection mark to a rotating object, the detectors can detect the rotation of the object without actually touching the object.

ElectroMagnetic Detector

MP Series - Ono Sokki

MP-900/9000 are chiefly used in conjunction with a detector gear mounted onto a rotating shaft by bringing the detector into proximity to the gear so that the detector outputs frequency signal of which is proportional to the rotational speed. So various types are available including low-priced, general purpose, oil proof and heat resistant types that you can make a choice for your usage.Signal cables (except attached-cable types), extension cables and connectors are sold separately.

Magneto-Electric Rotation Detector

MP-981/AP-981 - Ono Sokki

The MP-981 is a magneto-type detector using a hall element which is suitable for revolution (r/min) measurement from low speed to high speed.Magneto-type detectors use an internal hall element, a permanent magnet, DC amplifier, and voltage regulator and respond to flux, so that a rectangular wave form is derivable from much lower speed all the way though high speed.In addition, a signal indicator is provided in spite of the detector's compact design, making verification of operation and mounting position possible.Meanwhile, the AP-981 is the water and acid proof type, which conforms to Class ' of JIS C0920.

Optical Detector

LG-9200 - Ono Sokki

The LG-9200 is a non-contact type optical detector which emits red visible light and detects the reflected light from the rotating shaft. The reflection mark is used for the detection by affixing it on the rotating shaft. It enables detection at an angle. (reflective mark: HT-011 by Ono Sokki)The LG-9200 has a built-in compact amplifier and outputs the square wave (voltage) after waveform shaping.With a compact and light weight body, performances are upgraded compared to the previous model LG-916.(LG-9200 detection distance: up to 40 mm, response speed: up to 40 m/s)

F/V Converter

FV-1100 - Ono Sokki

The FV-1100 receives signal from a rotation detector or a similar device and outputs DC current or voltage signal proportional to its frequency. As the fluctuation of the input frequency signal is continuously converted to DC voltage, it is useful for measurement and recording of transient phenomena such as fluctuation of rotating speed, current velocity, frequency.
